Feature Tracking on the Unit Sphere [PDF]
Monthly Weather Review, 1995 Techniques used in a previous study of the objective identification\ud and tracking of meteorological features in model data are extended\ud to the unit sphere. An alternative feature detection scheme is described\ud based on cubic interpolation for the sphere and local maximization.\ud The extension of the tracking technique, used in the previous ...

Visualizing Three-Dimensional Ocean Eddies in Web Browsers
IEEE Access, 2019 Despite the importance of mesoscale eddies, and other three-dimensional features discernable in numerical simulations of ocean circulations, to the understanding of oceanic heat transport and climate change, there are few dedicated three-dimensional ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

A New Object Tracking Framework for Interest Point Based Feature Extraction Algorithms
Elektronika ir Elektrotechnika, 2020 This paper presents a novel object tracking framework for interest point based feature extracting algorithms. The proposed framework uses the feature extracting algorithm without making any changes and it relies on outlier detection, object modelling ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Joint tracking of features and edges [PDF]
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008 Sparse features have traditionally been tracked from frame to frame independently of one another. We propose a framework in which features are tracked jointly. Combining ideas from Lucas-Kanade and Horn-Schunck, the estimated motion of a feature is influenced by the estimated motion of neighboring features.
